Identifies the IsReadOnly property.

Assembly:  UIAutomationClient (in UIAutomationClient.dll)

Public Shared ReadOnly IsReadOnlyProperty As AutomationProperty

This identifier is used by UI Automation client applications. UI Automation providers should use the equivalent field in ValuePatternIdentifiers.

A control should have its IsEnabledProperty set to true and its IsReadOnlyProperty set to false before a client attempts a call to SetValue.

In the following example, a root element is passed to a function that returns a collection of UI automation elements that are descendants of the root and satisfy a set of property conditions.

'''--------------------------------------------------------------------
''' <summary>
''' Finds all automation elements that satisfy 
''' the specified condition(s).
''' </summary>
''' <param name="targetApp">
''' The automation element from which to start searching.
''' </param>
''' <returns>
''' A collection of automation elements satisfying 
''' the specified condition(s).
''' </returns>

Private Function FindAutomationElement( _
ByVal targetApp As AutomationElement) As AutomationElementCollection
    If targetApp Is Nothing Then
        Throw New ArgumentException("Root element cannot be null.")
    End If

    Dim conditionIsReadOnly As New PropertyCondition( _
    ValuePattern.IsReadOnlyProperty, False)

    Return targetApp.FindAll(TreeScope.Descendants, conditionIsReadOnly)

End Function 'FindAutomationElement
